global: make possible to set debug-flags dynamically

Adding {set,get}_debug_flags functions to the shell global object to
make possible to set this easily from looking class, making it easier
for developers and users to debug without having to restart the shell
with environment variables.

Debug flags in main are updated when the "debug-flags" property is
changed. I'm keeping this as a string-list so that it's easier to update.

main: increase the granularity of backtraces in SHELL_DEBUG

This is an optional extra, which allows to control the debug flags
with better granularity... Not indispensable, but nice to have IMHO.

This file is quite messy in alignment... This is aligned with other void functions, but let me know if you prefer in other way.
